If you're asking, means that you're willing to go through arkenfox configuration, setting up your rules and parameters, etc... So I'd say go for it. You can always go back to LibreWolf.

Yes, I think that's the point. Most browsers can be hardened, easily or not, but only few have actually good defaults.

That's just browsers with default settings. Firefox doesn't have a built in ad block, so it will always perform worse in that test. I guess FF + ublock origin + hardened settings (such as arkenfox) would perform like brave, if not better. For example, if you check android browsers, you see that Mull (a hardened fork of Firefox) performs great, even without ublock (that you can install as extension anyway).

I think that the problem was that I was using the left foot too much, because I'm too used to use the clutch a lot for doing these maneuvers. A friend of mine told me that the first thing to learn is that the left foot should rest. Anyhow, I think with some patience I could have done it, but I didn't feel safe to drive in the traffic like that for the first time.

Southern Europe, 34. I only know how to drive with manual transmission (I tried an automatic city car once, and I literally couldn't exit the parking spot). I'm too used to control the car with the clutch. I should learn though, because I use car sharing services, and they are progressively replacing their cars with automatic transmission ones.
